What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
We previously observed that circulating human neutrophils exposed to epithelial ovarian cancer (OC) ascites fluid supernatants (ASC) and malignant effusions from other tumors acquire T cell suppressor function. Collagen motifs ligate LAIR-1, an inhibitory SHP-1-dependent checkpoint broadly expressed on immune cells. We hypothesized that NC410, a bivalent LAIR-2 construct that inhibits LAIR-1-collagen binding, would rescue neutrophil-driven T cell non-responsiveness. NC410 remodeled ASC collagen resulting in neutrophil clustering and reduction in neutrophil-T cell contact, abrogated ASC-induced neutrophil trogocytosis of T cell membranes and rescued stimulated T cell proliferation. Mean ASC pro-collagen-1α levels were >100-fold greater than serum samples. In a single-center retrospective analysis, after adjusting for age, stage and optimal debulking, ASC pro-collagen-1α and serum sLAIR-1 levels were each associated with worse overall survival (OS), and ASC LAIR-2 levels were associated with better OS. Multispectral imaging of high-grade serous ovarian cancer and non-small cell lung cancer showed highly variable LAIR-1 staining in both tumor cell and immune infiltrates. The proportion of collagen-1-positive cells was highest among tumor cells and tumor-infiltrating immune cells versus stromal immune cells, raising the potential role of tumor-associated collagen limiting immune cell infiltration into tumor. Our results support further evaluation of circulating and tumor-associated collagen products and LAIR-1 and LAIR-2 as prognostic biomarkers in advanced OC and as biomarkers for clinical response to NC410 and to other collagen- and LAIR-directed therapies.
